What channel is March Madness on?

The broadcasting of all games in the 2018 March Madness tournament is a tag-team effort. Local CBS stations around the country are airing roughly one-fourth of the games, and the rest of the tournament is being divided up among Turner-owned pay TV channels TBS, TNT, and truTV. Here is a full TV schedule for March Madness 2018.

Games in the first and second rounds are being broadcast on one of the four different channels mentioned above. After that, to watch the Sweet 16, Elite 8, and 2018 Final Four, you must go to either CBS or TBS. Sweet 16 games are divided evenly between the two channels, while the two Elite 8 games on Saturday, March 24, are on TBS, and the two Elite 8 games on Sunday, March 25, are on CBS.

As for how to watch the Final Four, TBS is broadcasting all the games (the two NCAA March Madness semi-final matchups on Saturday, March 31, and the 2018 championship game, starting at 9 p.m. ET on Monday, April 2).
